Mataram: Health officials in West Nusa Tenggara (NTB), Indonesia, have confirmed a case of Influenza A (H3N2) subclade K, often referred to as “Super Flu,” in a 12-year-old girl. This detection highlights the continued evolution of influenza viruses and the importance of ongoing surveillance.
According to Lalu Hamzi Fikri, head of the NTB Provincial Health Office, the case was identified through influenza sequencing conducted on January 5, 2026. “Based on the results of the influenza sequencing examination received on January 5, 2026, one case of positive Influenza A (H3N2) subclade K was confirmed in a 12-year-old girl,” he stated in Mataram on Wednesday, January 14, 2026.
The confirmation followed the submission of eight samples from children exhibiting flu-like symptoms to the Surabaya Public Health Laboratory (Labkesmas) on November 10, 2025, for further analysis.
Following the initial case detected on November 5, 2025, the Health Office immediately launched an epidemiological investigation and implemented control measures. Close contacts and the surrounding environment were closely monitored for two incubation periods of the virus.
“The monitoring results showed no additional cases, so this cluster of cases was successfully controlled in November 2025,” Hamzi Fikri said.
Despite the successful containment of this particular cluster, officials caution that the risk of re-transmission remains, particularly with increased population mobility and the onset of the rainy season, which typically sees a rise in influenza cases.
To enhance preparedness, the Health Office is strengthening surveillance of Influenza-Like Illness (ILI) and Acute Respiratory Infections (ARI)/Pneumonia through the Early Warning and Response System (SKDR) across all healthcare facilities. Surveillance is also being conducted through sentinel ILI and Severe Acute Respiratory Infection (SARI) monitoring.
“SKDR data is analyzed weekly, and currently, there is no significant surge in cases of ILI, ARI, or pneumonia,” Hamzi Fikri added.

Hamzi Fikri emphasized the crucial role of public participation in prevention efforts. The Health Office urges the public to adopt Clean and Healthy Living Behaviors (PHBS), ensure adequate rest and nutrition, self-isolate when sick, wear masks, and seek medical attention if symptoms worsen.
The NTB Health Office also expressed appreciation for the swift response of healthcare workers and facilities in managing the case. Through coordination from community health centers to regional laboratories, the case was quickly identified and controlled.
“With the cooperation of all parties, we are optimistic that extraordinary events (KLB) can be prevented and the people of NTB can be protected,” Hamzi Fikri concluded.
